Sanctuary

You can receive Sanctuary after having completed the previous quest,With Friends Like These..., and talking to Astrid about some tasks you may be able to perform. She will direct you to Nazir and ask you to talk to him about some minor level contracts.

Nazir is the Redguard in red and may often be found standing in the main room of the cave in the Dark Brotherhood Sanctuary. Talk to him to advance the quest and you will receive three separate contracts, which are actually three separate contracts. In each instance, you should do your best to avoid killing in the public light as it often brings a large sum of bounty on your head and may take away the chance to get any added bonus to the reward of completing the contract.
